EDIT: this forwarder should do it, it has a nice loading bar and supports a splash image. Can you try if it has SDHC and nunchung bug solved?
EDIT2: forgot the link:

I don't have internet access at weekend (yeah, that sucks).
I'm pretty sure the Nunchuk bug and SDHC support are totally dependant to the used libogc and libfat (remember the nunchuk bug happened with the hbc too).
BTW ALL dol forwarders shold be open source, because I'm pretty sure the dol loading stuff is grabbed from gecko loader or loadmii, which are gpl licensed...
Another thing is that I dunno why the fuck we are using 18 files, I've just realized that we only need the one with the most characters.
I don't have my wii here(and where my wii is there's no internet), so I compile a forwarder, you try it for sdhc and nunchuk bug and tell me if that works.
Oh, and what kind of error messages do djdinamite's forwarders display?
Anyway I'd rather put the loading bar and just display the errors in case they ocur, keeping the screen as clean as possible.
